medSafe- A Blockchain based Electronic Health Record Application

For a long time, the medical business was the only one that accepted new technologies first. As a result, they now accept cloud computing to store patient records in the cloud, which they refer to as an "Electronic Health Record." They went to the cloud for a variety of reasons, including the inability to retain a traditional base of servers within them. Cloud computing is more secure and responsive. Their security is sometimes compromised. Blockchain is currently an interesting research topic, and the benefits it provides have been used by a range of applications. Blockchain will substantially improve the healthcare sector if it is connected with its means because to its robust nature in privacy and data protection. It is also a network-based technology that is decentralized. Each node will contain a duplicate of the data. Furthermore, EHR systems require a system with strong data security, integrity, and management challenges. Blockchain is made up of blocks that contain data. With an address, each block in the blockchain points to the next block. To put it simply, if someone tampers with the data in the block, the hash of the block changes, and every block in the blockchain becomes invalid. The purpose of this study is to demonstrate how blockchain can be connected with HER systems.
